Beschreibung
Zusammenfassung:	A dye dispersant containing a composition obtained by sulfomethylating lignin, in which the S content of a group represented by formula (1):-SO3M (in formula (1), M represents a hydrogen atom, a monovalent metal salt, or a divalent metal salt) is 1.0% by mass to 6.0% by mass, and the composition contains 1.5% by mass to 4.5% by mass of Na2SO4. 一种染料分散剂，含有对木质素进行磺甲基化而得到的组合物，其中，该组合物的由式(1)：-SO3M(在式(1)中，M表示氢原子、一价金属盐、二价金属盐)表示的基团的S含量为1.0质量％～6.0质量％，并且该组合物含有1.5质量％～4.5质量％的Na2SO4。
